AUXILIARY FLUID-'PRESSURE APPARATUS FOR `|NSTANTLY STARTING STEAM-ENGINES.

Y SPECIFICATION forming part of Letters Patent No. 730,157, dated June 2, 1903.

Application filed February 10, 1903. Serial No. 142,740. (No model.)

T all whom t may con/cern:

Be it known that I, KARL GUs'rAv MAXIL MILIAN REICHEL, a subject of the King of Prussia, Emperor of Germany, residing at 8A Olemensstrasse, Hanover, in the Province of Hanover and Empire of Germany, have invented new and useful Improvements Relating to Auxiliary Fluid-Pressure Apparatus for Instantly Starting Steam-Engines, of which xo the following is a specification.

My invention relates to apparatus designed for instantaneously working steamfvehicles and lire-engines, and has for its object to enable such vehicles and engines to be kept ready, on an alarm being given, for immediate work by the use of compressed air or gas, thus obviating the necessity of first getting up steam. The apparatus comprises a receptacle for compressed air or gas and a device 2o serving to regulate the pressure of the air or gas and included in thepipe which connects the receptacle with the steam generator. From the generator the compressed air or gas is supplied to the steam-engine until the pres- 2 5 sure of the steam got up in the generator reaches its normal pressure, the admission of the compressed air or gas to the steam-generator being interrupted by an automatic checking or stopping device likewise provided in 3o the said pipe.

In the drawings, Figure 1 is a general view of the apparatus, and Fig. 2 a section showing a detail.

The compressed air, carbonio-acid or like 3 5 gas is contained in the receptacle a carried on the vehicle. For regulating the supply of compressed air or gas which passes from this receptacle to the generator b through the pipe euse is made of a pressure-reducing device d of any known type. The pipe c is automatically cut off from the generator by a re turn-valve e included in this pipe, such valve being closed in opposition to the pressure of the air or gas by the steam in the generator on reaching the normal pressure. The returnvalve e, a section of which is represented in Fig. 2 to a larger scale, does not differ in construction from that of an ordinary returnvalve. It is connected with a stop-valve f of the common type, which serves for shutting od the pipe g leading from the generator to the steam-engine. v

What I claim as my invention, and desire to secure by Letters Patent, is

Apparatus of the character described, comprising a steam-generator, a receptacle fol compressed gas, a pipe connecting the generator with the saidfreceptacIe', meansvfor reducing the pressure of the gas coming from the receptacle and means for automatically shutting off the pipe from the generator on the steam in the latter reaching its normal pressure, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this speciiic'ation in the presence of two subscribing witnesses.
